Finding Function Values for Elements of the Domain

a tablet with a given problem and two questions

  Given: h(x) = 5x − 7  

What is the value of the function at 8? How can you verify the value graphically? To answer these questions, you will need to use both algebraic and graphic strategies. As you work through this topic, you will explore these strategies and learn how to apply them to find function values for elements of the domain.
